函数的参数类型定义

参数定义类型的方法

  • def person(name:str, age:int=33):
    print(name, age)

    • 函数定义在python3.7之后可用
    • 函数不会对参数类型进行验证

代码

# coding:utf-8
def add(a: int, b: int = 3):
print(a + b)
add(1, 2)
# add('hello', 'xiaomu')
def test(a: int, b: int = 3, *args: int, **kwargs: str):
print(a, b, args, kwargs)
test(1, 2, 3, 4, name='小慕')
def test2(a: int, b, c=3):
print(a, b, c)
test2(1, 3, 4)
